Abstract (en)

An improved process for the preparation of aralkyl monourethanes comprises the acid-catalyzed selective reaction of a divinyl aromatic hydrocarbon with an alkyl ester of carbamic acid, at low temperature. A high ratio of monourethane to the corresponding diurethane is obtained, especially if the reaction is terminated at low conversions.
